Abstract

The jack is particularly for motor vehicles, having a quadrilateral linkage operated by a screw rotated by a hand crank, together with a base testing on the ground and a lifting member bearing against the vehicle. The linkage is formed by two pairs of arms of unequal lengths, although each arm in one pair is of equal length to the one opposite it in the other. Thus the screw which forms the diagonal of the quadrilateral is inclined upwards. Each half of the quadrilateral, on opposite sides of the diagonal can comprise two arms of different lengths, pivoting together on pins also accommodating the base and the lifting member.
